Pixel-level Signal Modelling with Spatial Correlation for Two-Colour Microarrays

Ekstrøm, Claus; Bak, Søren; Rudemo, Mats - In: Statistical Applications in Genetics and Molecular Biology 4 (2007) 1, pp. 6-6

Statistical models for spot shapes and signal intensities are used in image analysis of laser scans of microarrays. Most models have essentially been based on the assumption of independent pixel intensity values, but models that allow for spatial correlation among neighbouring pixels can...

Proof load designs for estimation of dependence in a bivariate Weibull model

Johnson, Richard A.; Lu, Wenqing - In: Statistics & Probability Letters 77 (2007) 11, pp. 1061-1069

A proof load design is useful for estimation of the dependence between two strength properties of a unit when either property can only be measured by loading to failure. Here we extend the application of the proof load design to estimate the parameters of a bivariate Weibull distribution. An...

Count data models with unobserved heterogeneity : an empirical likelihood approach

Boes, Stefan (contributor) - 2007

As previously argued, the correlation between included and omitted regressors generally causes inconsistency of standard estimators for count data models. Using a specific residual function and suitable instruments, a consistent generalized method of moments estimator can be obtained under...

Analyzing type II censored data obtained from repetitious experiments

Tong, Lee-Ing; Yang, Chien-Hui - In: Journal of Applied Statistics 33 (2006) 1, pp. 49-63

/product. However, censored data are often observed in product lifetime testing during the experiments. After implementing a repetitious … experiment with type II censored data, the censored data are usually estimated by establishing a complex statistical model …. However, using the incomplete data to fit a model may not accurately estimates the censored data. Moreover, the model fitting …
